Question

find surface area of cudoid whose side is length is 15and breadth is 14 height is 12

Answer 1

Length = 15 cm 
Breadth = 14 cm
Height = 12 cm
We know TSA of cuboid = 2(LB+BH+HL)
=> 2(15x14 + 14x12 + 12x15)
2(210 + 168 + 180)
2 X 558 = 1116 cm sq
Hence Surface Area of cuboid = 1116 cm square
